Has anyone used reactigFoam for Methane-Oxygen combustion. I am trying to simualte a methane oxygen flame under atmospheric pressure. There is an inlet for both methane and oxygen. The issue is it does not ignite, even though the initial temperature is about 1500 K.

I also tried using enthalpySource and somehow that also does not help igniting the mixture.

If anyone has simulated, then it would be help ful if you could share your casefiles and solvers.
